A critical flaw in the Afghanistan peace talks was the disconnect between the negotiator and the President. A negotiator must be in the room where decisions on troop levels and other forms of leverage are made; without this direct line, their efforts are fundamentally undermined.

An empire's definitive decline is marked by a "Suez Canal moment"—a failure to control a key strategic point. The chaotic US withdrawal from Afghanistan, not the current Iran conflict, may have already been that irreversible signal of diminished global power.

When a government declares a military operation a 'success' but immediately pauses follow-on activities to 'resume negotiations,' it's a strong indicator the initial action failed. The public declaration of victory is often a face-saving measure to exit a situation where objectives were not met.

For two decades, Afghanistan was a top U.S. priority, consuming vast resources. The fact that the U.S. could completely disengage with no apparent negative strategic consequences suggests the threat was exaggerated or the core mission had already been achieved long before the withdrawal.

The U.S. killing of Taliban leader Mullah Mansur, who was considered more transactionally-minded, had the unintended consequence of strengthening the group's most conservative wing. The Taliban chose a less divisive, more hardline successor, showing how targeted killings can backfire.

A core, flawed assumption of the Afghanistan campaign was that Pakistan would eventually become an ally and deny safe haven to the Taliban. The U.S. never held Pakistan accountable for its role as a sanctuary and logistics hub, which fatally undermined the entire operation.

Nations like the US and USSR prolong involvement in failed conflicts like Afghanistan primarily due to "reputational risk." The goal shifts from achieving the original mission to avoiding the perception of failure, creating an endless commitment where objectives continually morph.

The West's five-year strategy of using sanctions, reduced aid, and frozen assets to pressure the Taliban into moderation has not worked. This failure is forcing a reluctant strategic shift, with countries now engaging on issues like migration and counter-terrorism out of necessity.

The core weakness of U.S. foreign intervention isn't a lack of military or economic power, but a lack of seriousness about the aftermath. The U.S. lacks the patience, humility, and stamina for the difficult, unglamorous work of post-conflict planning and nation-building, dooming interventions to failure.
